EJECTING DEVICE FOR DOUBLE-BARREL GUNS.

Specification of Letters Patent.

Application filed october 16, 1918. Serial No. 258,338.

To all whom it may concern:

Be it known that I, GEORGE H. Grooms-s, a citizen of the United States,residing at Ilion, inthe county of Herkimer and the t9 a gun ofthisftype shown in my applicatlon filed August 24 and bearing SerialNumher 251,259, to which reference may be had for details ofconstruction omitted from this application.

The present invention has for its object the discharge of shells fromeither one "or both barrels, and. for the preliminary starting of ashell to prevent stlcking.

The invention also consists in the novel features of constructionhereinafter described, pointed out in the claims and shown in theaccompanying drawings in which Figure 1 is asectional view showing thegun in open pos tion. I

Fig. 2 is a detail sectional view showing the position occupied by theparts when the gun is only partly opened.

Fig. 3 is a section along the line of the opening, looking toward thegun muzzle, the gun bein closed.

Fig. 4 1s a detail plan view of a portion of the gun frame showing theejector hammers and cooking levers.

Fig. 5 is a perspective view of one of the main hammers.

Figs. 6, 7, 8 and 9 are detail views of e ectors. i

Fig. 10. is adetail side view of apin. I

In the drawings 1 designates the gun frame, 2 and 3' the upper and lowerbarrels, 4 one of the main hammers and 5 a cam carried thereby.

The ejecting devices LIB mounted in the gun frame on opposite sides of.the concaved cut made to receive the lower; barrel 3. As these parts areduplicated omopposite sides a description of one set will sufiice forboth, and I have more fully shown and will therefore describe the lefthand set, that is the ejecting device on the left hand side of the gunlooking toward the muzzle.

These consist of the following parts:

Ejector hammers 6, one onea'ch side asin Fig. 4, ejector sears 9,springs 10, cocking levers 11, ejectors l2 and 13; theejector 13 beingon the left hand side, ejector stop screws 14, but one of which appearsin the drawings, pins 15 for the springs 10 and sear springs 16. 7

From the drawings it will be noted that the ejector hammers have alower, forward shoulder 7, and are recessed just to the rear of theirpivotal point as at 8'. There is also shown the main hammer cockinglever 17, left hand side.

The main hammers carry laterally projecting pins 4. The right and lefthand parts of the ejecting mechanism are dupli-,

cates with the exception of theejectors 12 and 13. These comprise shankportions with heads 12* and 13 and there is a slight difference in theshape of the heads, the head 12 being also the larger, to cooperate withthe shell of the upper barrel.

It will be understood that if the upper barrel only is fired only theright hand ejector will eject the shell, the left hand ejector ridingout tofull limit of its stroke with the shell unfired and back againwhen the gun is closed. If the left hand mechanism only isfired, asdescribed in the appl cation above referred to, only the shell in thelower barrel will be ejected, but if both barrels are fired both shellswill be ejected at the same time.

Patented July 8, 1919.

- From Fig. 2 it will be noted that the left hand ejector hammer 6 isheld in its cocked position by its sear 9, the hammer getting I itsstriking power from the V-spring 10 which rests at one end in a cut inthe frame and the other end bears on the hammer below its pivotal point.The spring is held in place at the rear end by the pin 15 which is 1 theejector hammer der 7 by sear spring 16, when" the hammer 6 has beenpressed back a suflicient distance. To pull the sear from said shoulderat the proper moment, that is when the gun has been fully opened,the're'ar end portion of the sear 1s bent u wardly and engages the bossor pin 4 on t e main hammer 4 so that when the is opened and the hammer4 is carried to full cock pin 4 is thrown upwardl and'carries the rearend of sear 9 with it, thereby drawing the opposite end of the sear awayfrom the ejector-hammer 6, as shown in Fig. 1.

This action takes place as soon as the gun is open far enough to allowempty. shells to the barrels from the frame it is necessary that theejector hammers be in uncooked position, due to the raising of the searend by the boss 4?. The object of thisis to assure that the strain isoff the ejector springs when the gun 1s packed away 1n gun case therebyreducing the proportion of broken and damaged springs.

After the barrels have been disconnected from the gun frame the operatorcan then let down t e main hammers by simply pulllng the trigger twice,in this way straincan be taken off all the springs in the gun when laidaway in its case.

Th s does not make it inconvenient to disengage the barrels as the guncocks as easily wlth the fore-end off as it does with it on, and thecooking of gun and disengagement of the frame ment.

In ejector devices it is necessary to have a movement in advance of the.final'. kickp that causes ejection of the shells to start sticklngshells, termed primary extraction. This gained by the ejector hammers 6taklng a bearing at 18 When the gun is belng opened. Thi bearing backsup the e ector hammerand in turn forces ejector 12, or 13 as the casemay be, to start the shell out of the chamber of the barrel about oneeighth of an inch before ejection takes place. This movement takes placewhen the gun isppened' to a position between those shown in Figs. 1 and2, and at such time as the barrels swinging on their pivot 19 wouldcarry the ejector stems into alinement with the ejectorhammers, or to aposi-' t1on approaching that shown in Fig. 1;

' It is elieved that from the drawings and description above given theinvention w ll 9 it strikes ejector 13, "the left areboth done with onemovebe cleafly understood and its advantages made obvious.

What I claim is 1. In devices of'the kind. described in double barrelguns, ejector hammers, slid- .able ejectors adapted to be struck by saidhammers, stops for said ejectors, spring pressed ejector hammer sears,cocking levers engaging the said hammers, V-sprmgs engaging the cockinglevers and the hammers, and main hammers adapted to engage the ejectorhammer sears, and to disengage them from the ejector hammers as the mainhammers are drawn to full cocked position. 7

2. In a device of the kind described, ejector hammers pivoted in theframe on opposite sides of the barrels and having shoulders andrecesses, cocking levers having their forward ends engaging saidrecesses, and their rear ends pressed downward by the water table whenthe n is closed,

sears adapted to engage'the e ector hammer shoulders, springs to lmpartstriking movement to the hammers, ejecting devices 1n position to bestruck by said .hammers, mam

- hammers controlling movement of the scars,

and-stops for the ejectors.

3. In ejector devices for double barrel guns, slidable ejectors arrangedin the frame adjacent the barrels, stop screws llmltlng outward andrearwardmovement of the. ejectors, spring actuated ejector hammers,

said hammers havin an initial bearing on I the gun frame as t a gun isopened and engaging the ejectors durlng sa1d opening movement therebyimparting prellmlnary outer movement to-the ejectors, sears engaging thehammers normally and releasing them as the gun is opened, and cockinglevers engaging the hammers and held, during closed position of the gunby the water table, in normal pos1t1on.

4. In ejector devices for double barrel guns, ejector hammers, springsfor actuating said hammers, cocking levers engagmg the hammers andnormally held in pos1t1on by the Water table of the n, sald levers beingreleased by openlng o the gun, spring pressed sears engagmg the hammers,said sears being disengaged from the hammers on opening of the gun, andslidable e ectors in position to be struckand forced rearward by thehammers when released by the sears, asand for the pur ose set forth. Intestimony w ereofI have afiixed my I signature.
